2. Safety
2.1 Appropriate Usage
The „Batter Backup Distribution“ is an automatic transfer switch, suitable to the SMA „Flexible
Storage S stem“, functionall in communicating to:
- SI 4.4M-12 / SI 4.4M-13 (Sunn Island 4.4M) from Firmware 1.00.xx.R
- SI 6.0H-12 / SI 6.0H-13 (Sunn Island 6.0H) from Firmware 1.00.xx.R
- SI 8.0H-12 / SI 8.0H-13 (Sunn Island 8.0H) from Firmware 1.00.xx.R
- in combination with either
 HM-20 (Sunn Home Manager 2.0) from Firmware 2.00.00.R
or
 EMETER-20 (SMA Energ Meter) from Firmware 2.0.15.R
The Sunn Island S stem controls this automatic transfer switch (hereinafter called „Batter
Backup Distribution“ or shortened „BBD“) and creates an island network in case of main power
blackouts.
The Batter Backup Distribution does an all-pole disconnection and isolates the PV-S stem and the
load to the public network in a safe wa .
The Batter Backup Distribution is onl certified for TT- and TN-S grids!
Basicall , ou ma onl use the Batter Backup Distribution within the SMA „Flexible Storage
S stem“ in combination with SMA – Sunn Island 4.4M/6.0H/8.0H. Consult the corresponding SMA
paperwork (planning guidelines, installation-guides and all the other documents, which are
applicable for our countr and project).
Within a 3-phase s stem ou have to do a master/slave configuration of the Sunn Island’s. The
master is doing all the switching operations and controls the contactor’s activities. For more
details ou have to stud the SMA paperwork!
Do not exceed the maximum power input and connection power. Please note accordingl the
technical specifications of the various t pes (at chapter 18).
Do not use the Batter Backup Distribution for purposes other than those described here.
Alternative uses, modifications and the installation of components void the warrant claims and
operation permit.

2.2 Safety Instructions
Electric shock due to high voltages in the Batter Backup Distribution when connecting the device!
Death or serious injuries!
 All work on the Batter Backup Distribution must be performed b a qualified
personnel.
 Work on the Batter Backup Distribution should onl be carried out as described
in this manual.
 Observe all specified safet precautions
Construction and design of the Batter Backup Distribution is due to user-friendl handling of
circuit breakers, fuse holder and RCCB’s (residual current operated circuit breakers).
In addition (if the SMA Energ -Meter or the SMA Home Manager is included) ou are able to
notice different operational state of the s stem, shown b the LED’s.
Please consider the relating SMA Original instructions of the Energ -Meter or Home Manager.

4. Electrical Connection
4.1 Installation Energy Meter / Home Manager
Instead of the Energ Meter / Home Manager, screw terminals are used as placeholders.
An Energy Meter / Home Manager is not included in the scope of delivery and must be
retrofitted!
The terminals are capable of carr ing currents, whereb the basic function oft he automatic
transfer switch is given. Thus, the automatic transfer switch can alread be connected and tested
without Energ Meter / Home Manager.
During installation, note the positioning of the Energ Meter / Home Manager to the cover strips
of the distribution board.
When installing the Energ Meter / Home Manager, observe the maximum permissible torque of
2.0 Nm!
